Petrus developed the phone in an effort to solve the country’s wireless problems.
A Namibian 12th grade student has invented a phone that does not require a sim card, therefore does not need airtime to make calls, making it completely free. Simon Petrus, from Namibia’s Ohagwena Region, a student at Abraham Iyambo Senior Secondary School, has become a household name in the southern African country for his ingenious inventions in the past year. Petrus developed the phone in an effort to solve the country’s wireless problems, using spare parts from a phone and a television set, according to How Africa. The phone features a charger socket, light bulb and fan and functions off of radiator power, with the ability to make calls to anywhere using radio frequencies. The prototype is quite large at this stage, encased in a box, made up of a radio system, with the capability of viewing one TV channel. Last year, Petrus won a national gold medal for developing a machine that both dries and cools seeds. His latest invention has been in the works for two years and he hopes to develop the phone further. Petrus’ parents, although unemployed and struggling, financed their son’s projects, and the hope now is that others will help to take the project further. According to The Namibian, other student inventors, such as Joshua Nghaamwa, have had a national impact. Nghaamwa reportedly created a satellite from radios and cellphones. The satellite is compact and allows connectivity to a cellphone, router or modem that increases internet speed. He hopes to introduce the device throughout Africa to make the internet more accessible throughout the country.
